Swimmers, surfers warned about contaminated water

County health officials are warning water enthusiasts that beaches up and down the coast may be contaminated with urban runoff after recent heavy rains.

A general advisory warning swimmers, surfers and other ocean users about significant bacteria levels in the water, especially near storm drains, was issued by San Diego County’s Department of Environmental Health over the weekend and will remain in effect for up to 72 hours following rain.

Urban runoff can contain high levels of bacteria from animal waste, soil and decomposing vegetation. Coastal storm drains have permanent signs warning of runoff but signs are not routinely posted for general advisories.

Water activities should be avoided for three days after the last storm.
